I designed and developed several end-user functionalities while complying with the highest possible security standards.

Middle Office Implementation for a Bank

Designed and implemented the entire middle office solution for a major Bulgarian bank.

The solution had to compile payment orders from a horde of systems and then process them. Bank employees could then monitor the payment orders in real-time through a website and take manual control of the process.

Identified problematic areas in the existing solution and proposed and implemented new technologies and solutions.
